As noted by Kieran, one of Joanne's biggest TV roles was in Grace & Favour, the 1992-1993 sequel to Are You Being Served (RIP David Croft). Miss Lovelock appeared in every episode and was particularly admired by Captain Peacock, while the women tended to bitch about her. It's not hard to see how she got the Stiletta role after this - her character is quite similar in voice and attitude, not to mention the innuendo-laden remarks!
